Capel Technology is well equipped to meet your needs; from providing you with bare flexible circuits and Flex-rigid boards to sub-assemblies, to complete box builds and can support you in finding other partners that can address additional needs that you may have.
Single layer flex
Circuit is the most basic and consists of a flexible polyimide film laminated to a thin sheet of copper. The copper layer is then chemically etched to produce a circuit pattern specific to your specific design requirements. A polyimide coverlay is then added for insulation and environmental protection of the circuit.
Double sided flex circuit
Double sided flex circuit is a circuit having two conductive layers, one on each side of the base layer of polyimide within the circuit. Trace patterns, specific to your needs, can be created on both sides of the substrate film and can be connected where desired with copper plated through-holes. The plated through holes make electrical connections between the two layers.
Multi layer flex circuit
multi layer flex circuit combine several single-sided or double-sided circuits with complex interconnections, shielding and/or surface mounted technologies in a multi layer design. The multi layers may or may not be continuously laminated together throughout the production process. If your design needs require maximum flexibility, continuous lamination may not be appropriate. Multi layer circuits are an effective solution when confronted with design challenges such as: unavoidable crossovers, specific impedance requirements, elimination of crosstalk, additional shielding and high component density.
Rigid flex circuits
Rigid flex circuits have been used in the military and aerospace industries for more than 20 years. In most rigid flex circuit boards, the circuitry consists of multiple flexible circuit inner layers selectively attached together using an epoxy pre-preg bonding film, similar to a multilayer flexible circuit. However, a multilayer rigid flex circuit incorporates a board externally, internally or both as needed to accomplish the design.
Rigid flex circuits combine the best of both rigid boards and flexible circuits integrated together into one circuit. The two-in-one circuit is interconnected through plated thru holes. Rigid flex circuits provide higher component density and better quality control. Designs are rigid where extra support is needed and flexible around corners and areas requiring extra space.
While the design options are endless when combining rigid boards with flexible circuits, we have provided you with rigid flex combinations that are most commonly utilized.
